Check USB connection Check that the USB cable is not dirty. Fine dust or dirt particles may prevent recognition. If the Walkman’s WM-PORT or USB cable terminal is dirty, clean it with a soft cloth. Check that the PC’s USB ports recognize the Walkman. Connect the Walkman to all of the PC’s USB ports and check that they recognize the Walkman. If you are using a USB hub, remove it and try connecting the Walkman to the PC’s USB ports directly to check that they recognize the Walkman.
